WASHINGTON — As an AIDS activist in the early 1990s, Gregg Gonsalves traveled to Washington to challenge the Food and Drug Administration.

Gonsalves was part of the confrontational group AIDS Coalition to Unleash Power, which staged protests outside the FDA's headquarters, disrupted its public meetings and pressured its leaders into speeding up the approval of experimental drugs for patients dying of AIDS.

A quarter century later, Gonsalves still travels to Washington, but with a different agenda: to defend the FDA.
